초록
The resistance test of a high speed craft such as planing ship is performed with a high speed towing carriage instead of ordinarytowing carriage because of the speed limitation. In the resistance test using high speed towing carriage, the model ship is fixed to thecarriage to restrain the running attitude for enough measuring time. Such method is called fixed model test method. In the fixed modeltest method, to get the appropriate running attitude, the model test is iteratively repeated until the trim moment and lift force are closeto zero. In this research, trim free model test method is investigated to reduce the number of iteration. And, the limitation of towingspeed range in the trim free model test method is investigated.
